1. A catheter assembly comprising:
a catheter possessing a distal end, a proximal end and a proximal end portion; a catheter hub fixed to the proximal end portion of the catheter, the catheter hub possessing a proximal-most end; a hollow inner needle positioned inside the catheter and removable from inside the catheter, the needle possessing a distal end, and the needle including a needlepoint at the distal end of the needle; a gripping member connected to a proximal portion of the inner needle and extending in a longitudinal direction; a catheter operating member connected to the catheter hub and movable in the longitudinal direction relative to the inner needle, the catheter operating member including an operating portion; the operating portion of the catheter operating member possessing a part to which a force is applied by the user to move the catheter relative to the inner needle; a guide wire slidably positioned in the inner needle and possessing a distal end, the guide wire possessing a length longer than the inner needle and longer than the catheter, the guide wire being configured so that the distal end of the guide wire projects distally beyond the needlepoint during use of the catheter assembly; a wire operating member connected to the guide wire and movable in the longitudinal direction relative to the inner needle and the catheter, the wire operating member including an operating portion; the operating portion of the wire operating member possessing a part to which a force is applied by a user to move the guide wire relative to the catheter and the inner needle; and the part of the operating portion of the catheter operating member to which the force is applied by the user being positioned distal of the proximal end of the catheter hub in an assembled state of the catheter assembly before use of the catheter assembly. |
